How many years does lithium battery last?

The lifespan of lithium batteries can reach up to more than 6 years.

Battery life, in other words, how long the battery lasts. Lifespan refers to the number of times the battery can withstand wattage and full discharge before the battery capacity drops to a certain specified value under a certain charging and discharging system.

After each cycle is completed, the battery capacity will be reduced, as well as its lifespan. Lifespan is not equal to number of charges. If the battery is charged multiple times during a charge-discharge cycle, the battery actually depletes in a single cycle.

And the number of charging and discharging times of lithium batteries is basically about 300-500 times. During use, lithium batteries may be partially discharged, but not completely. Because a lithium batterym too charged can cause excessive internal chemical reactions.

Battery Features:

1. The weight of high energy density lithium-ion batteries is half that of nickel-cadmium or nickel-metal hydride. batteries of the same capacity, and the volume is nickel 20 ~ 30% cadmium and 35 ~ 50% nickel metal hydride.

2. High voltage The operating voltage of a lithium-ion battery cell is 3.7 V (on average), which is equivalent to three nickel-cadmium or nickel-metal hydride batteries connected in series.

3. Non-polluting lithium-ion batteries do not contain harmful metal substances such as cadmium, lead and mercury.

4. Lithium-ion batteries do not contain lithium metal, so they are not subject to air transport restrictions such as the ban on carrying lithium batteries on airplaness of passengers.

5. No memory effect The memory effect refers to the phenomenon that battery capacity decreases during the charge and discharge cycle of nickel-cadmium batteries. This effect does not exist with lithium-ion batteries.
